目前,在金刚石钻进过程中,正确选择钻进规程,提高钻头寿命,还存在很大潜力.据统计,吉林某队所使用的420个钻头中,非正常磨损的占60%;湖北地质局使用了700个钻头,非正常磨损的占40%;新疆地质六队使用的63个钻头中,非正常磨损占77.8%;河南二队1978年共使用了191个钻头,非正常磨损占22.5%.一般来说,非正常磨损中烧钻占12～13%,其它如 At present, diamond drilling process, the correct choice of drilling rules to improve bit life, there is still great potential.According to statistics, a team of Jilin used 420 drill bits, 60% of non-normal wear and tear; Hubei Bureau of Geology 700 drills were used, 40% of which were not normal wear and tear; among the 63 drills used by the Xinjiang Sixth Team, 77.8% were non-normal wear and tear; 191 drills were used in Henan Second Team in 1978, with non-normal wear and tear accounting for 22.5% In general, non - normal wear and tear in the burns accounted for 12 to 13%, others such as
